摘　　要：早优11是广西农科院水稻研究所以新育成的野败型不育系早A与恢复系科11配组而成的感温型早熟杂交稻组合。该组合产量较高,感稻瘟病和白叶枯病,米质达到国标1级优质稻谷标准。2006年2月通过广西农作物新品种审定。Zaoyou 11 is a thenno-sensitive early maturing hybrid rice combination derived from the newly developed WA type CMS line Zao A and the restorer line Ke 11. It showed a high yielding ability, but it was susceptible to blast and bacterial leaf blight in the regional trials of Guangxi during 2003-2005. Its grain quality was very good. The analysis resuits showed that it met the state quality standards for the first grade fine quality cooking rice of indica variety.
